The time and costs saving technology of blind riveting is simple. The materials to be riveted only need to be reached from one side, which explains the term "blind" riveting. The actual installation process is quick, simple and repeatable without the need for skilled labour.
Rivets are made of two parts,the body and the mandrel. The body is expanded when the mandrel is withdrawn as the rivet is set, and it is this part which clamps the materials together. The function of the mandrel is to deform the body of the rivet. The mandrel is therefore always stronger than the body. The mandrel breaks off at it a predetermined
breaking point. This breaking point ensures that the mandrel breaks off at the right moment so that the body is correctly formed, and the materials are permanently clamped tightly together.
